Subject: [PATCH v3 10/17] Use semop syscall for Linux implementation
Date: Tue, 08 Nov 2016 20:30:00 -0000 [thread overview]
Message-ID: <1478637007-31212-11-git-send-email-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <1478637007-31212-1-git-send-email-adhemerval.zanella@linaro.org>
Changes from previous version:
- Remove semop from syscalls.list.
--
This patch add a direct call to semop syscall if it is supported by
kernel headers.
Checked on x86_64, i686, powerpc64le, aarch64, and armhf.
* sysdeps/unix/sysv/linux/alpha/syscalls.list (semop): Remove.
* sysdeps/unix/sysv/linux/arm/syscalls.list (semop): Likewise.
* sysdeps/unix/sysv/linux/generic/syscalls.list (semop): Likewise.
* sysdeps/unix/sysv/linux/hppa/syscalls.list (semop): Likewise.
* sysdeps/unix/sysv/linux/ia64/syscalls.list (semop): Likewise.
* sysdeps/unix/sysv/linux/microblaze/syscalls.list (semop): Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (semop):
Likewise.
* sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list (semop):
Likewise.
* sysdeps/unix/sysv/linux/x86_64/syscalls.list (semop): Likewise.
* sysdeps/unix/sysv/linux/semop.c (semop): Use semop syscall if it is
defined.
